[jira] [Updated] (HAMA-821) K-Means writes only k records as a
output
[ https://issues.apache.org/jira/browse/HAMA-821?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Edward J. Yoon updated HAMA-821:
--------------------------------
Description:
KMeans writes only k records, because 276 line at KMeansBSP overwrites the value for the key. I'm sure it was not intended..
And, many people ask me about meaning of input and output of KMeans. We need to make K-Means example output lines more readable like,
{code}
13/11/25 17:34:04 INFO kmeans.KMeansBSP: Finished! Writing the results...
[5.1, 3.5, 1.4, 0.2] belongs to cluster 2
[4.9, 3.0, 1.4, 0.2] belongs to cluster 2
[4.7, 3.2, 1.3, 0.2] belongs to cluster 2
[4.6, 3.1, 1.5, 0.2] belongs to cluster 2
[5.0, 3.6, 1.4, 0.2] belongs to cluster 2
....
{code}
was:
KMeans writes only k records, because 276 line at KMeansBSP overwrites the value for the key. I'm sure it was not intended. I'll fix this..
And, make K-Means example output lines more readable (like mahout):
{code}
